When communicating via the parallel port
(refer to Figure 12), the previously
mentioned parameters are not considered.
Refer to page 46 to configure the
communication parameters for the printer.
The values selected must be the same as
those used by the host equipment connected
to the printer.
For serial and parallel pinout and technical
information, refer to the Appendix on
page 85.
Cabling Requirements
Data cables must be fully shielded and fitted
with metal or metalized connector shells.
Shielded cables and connectors are required
to prevent radiation and reception of
electrical noise.
To minimize electrical noise pickup in the cable:
�
Keep data cables as short as possible.
�
Do not bundle the data cables tightly with the power cords.
�
Do not tie the data cables to power wire conduits.
NOTE: Zebra printers comply with FCC “Rules and Regulations,”
Part 15, for Class B Equipment, using fully shielded data cables.
Use of unshielded cables may increase radiated emission above the
Class B limits.
NOTE: RS-422 and RS-485 applications should use twisted shielded
pairs as recommended in the Appendix of the TA/EA.-485
Specification.
